Anyway, first year is a lot more calm than you're led to believe. It's not 9-5 every day until third year really (and that's still excluding Wednesday afternoon, which you'll get free every single week until fourth year). In first year it's more like 9-3 or 11-5, I'd say only had about three 9ams per week. Some weeks you'll straight up have a day off, as they can't take everyone to the farm at the same time, so you'll spend a couple of days up there and have a day off every week for a few weeks as other groups go up.
The timetable varies every week so the time you'll finish on a Friday will vary. I will say that we very rarely had a 9am on Monday morning, but that's the only trend I really remember.
